Description
本新型涉及氣動釘槍的結構配置技術，特別有關一種配置有梭動閥的氣動釘槍連續擊釘裝置。The utility model relates to a structural arrangement technology of a pneumatic nail gun, in particular to a pneumatic nail gun continuous nailing device equipped with a shuttle valve.
氣動釘槍是一種仰賴高壓空氣作為動力源，以便驅動活塞下移擊釘及上移復位的氣動手工具。一般氣動釘槍的擊釘方式，可區分為順序式驅動(Restrictive actuation)及接觸式驅動(Contact actuation)兩種模式，其中：Pneumatic nail gun is a pneumatic hand tool that relies on high-pressure air as a power source to drive the piston down the nail and move it up and down. Generally, the nailing method of the pneumatic nail gun can be divided into two modes: a restrictive actuation and a contact actuation, wherein:
順序式驅動模式，是指操作者必須先將安全滑桿或桿上的敲擊座壓觸於待釘結的工作物面，以推觸扳機的內簧片(或稱內扳機)，而後壓扣扳機，使扳機內簧片被連動而去啟動扳機閥進行擊發釘件的模式。在此模式下，每當操作者欲二次擊釘時，至少必須遵循先釋放扳機而後再重複壓扣扳機的順序，才能再次擊發釘件。當操作者違反此一驅動順序，亦即先壓扳機而後壓安全滑桿或桿上的敲擊座時，扳機內簧片無法被連動，且扳機閥無法被啟動，藉此抑制釘件被擊發。The sequential drive mode means that the operator must first press the tapping seat on the safety slider or the lever against the work surface to be nailed to push the inner reed (or inner trigger) of the trigger, and then press. The trigger is pulled so that the trigger inner reed is interlocked to activate the trigger valve to fire the nail. In this mode, whenever the operator wants to hit the nail twice, at least the order of releasing the trigger and then repeating the trigger can be repeated to fire the nail again. When the operator violates this driving sequence, that is, when the trigger is first pressed and then the safety slider or the knocking seat on the rod is pressed, the trigger inner reel cannot be interlocked, and the trigger valve cannot be activated, thereby suppressing the nail being fired. .
接觸式驅動模式，是指操作者依循先持續壓扣扳機不放，隨後將安全滑桿或桿上的敲擊座朝向待釘結的工作物面位置進行連續接觸式的敲擊，使扳機內簧片在每一次敲擊時皆能被連動上揚，進而逐次啟動扳機閥，進行可連續的接觸式擊釘運作。在此模式下，也容許操作者將安全滑桿或桿上的敲擊座先行壓持於待釘結之工作物面上，以連動內簧片上揚，隨後進行單次或連續壓扣扳機動作，以便於工作物面上釘結單支或多數支釘件。In the contact drive mode, the operator follows the continuous pressing of the trigger, and then the tapping seat on the safety slider or the rod is subjected to a continuous contact type of tapping on the working object surface to be nailed, so that the trigger is inside. The reed can be moved up and down every time it is struck, and then the trigger valve is activated one by one to perform continuous contact nailing operation. In this mode, the operator is also allowed to press the safety slider or the tapping seat on the rod first on the work surface to be nailed, so as to interlock the inner spring to rise, and then perform a single or continuous press trigger action. In order to nail a single or a plurality of nails on the work surface.
由上述可知，無論是順序式驅動模式或者是接觸式驅動模式，都必須仰賴槍體上配置有安全滑桿及扳機(包含內扳機)，以便於管制槍體內由盤狀活塞構成的主氣閥，在適當時機，能開閥導引高壓空氣驅動氣缸內的擊釘活塞下移擊釘，並且能關閥轉換高壓空氣的氣路，進而驅動氣缸內的擊釘活塞上移復位。It can be seen from the above that whether it is the sequential drive mode or the contact drive mode, it is necessary to rely on the safety slider and the trigger (including the inner trigger) on the gun body to control the main air valve composed of the disc piston in the gun body. At the appropriate time, the valve can be opened to guide the high-pressure air to drive the nail under the nail to move the nail, and the valve can be switched to switch the high-pressure air, thereby driving the nail piston in the cylinder to move up and reset.
此外，在自動化連續釘結的使用端需求下，氣動釘槍已可被配置於自動機具中，進行自動化的按壓扳機操作以及將安全滑桿或敲擊座自動地壓觸於待釘結的工作物面的操作，其中利用安全滑桿的壓觸工作物與否，來作為扳機按壓時的安全開關，仍是不可缺少的安全必要配置；但是，當扳機被安全滑桿觸動而開啟保險時，目前相關技術中，比較缺少能直接透過使用者的單次按壓扳機，或者是透過自動機具的單次按壓扳機，而產生一種連續式驅動(Automatic actuation)的擊釘操作模式。在此種連續式驅動擊釘的操作模式的需求下，不論是操作者或自動機具，皆只需按壓單次扳機，即可驅動擊釘活塞在氣缸內往復移動，進而自動地連續擊釘，因此有別於上述順序式驅動(Restrictive actuation)的操作模式下，操作者需釋放扳機後再二次按壓扳機，才能進行連續擊釘。因此，將可省下連續按壓扳機所需的手動負擔或自動機具之動作組件的往復控制負擔。In addition, pneumatic nail guns can be configured in automated implements for automated end-to-end nailing applications, for automated push trigger operation and automatic pressing of safety slides or tapping seats to the work to be nailed. The operation of the object surface, in which the safety switch of the safety slider is used as the safety switch when the trigger is pressed, is still an indispensable safety necessary configuration; however, when the trigger is activated by the safety slider, the safety is activated. At present, in the related art, there is a lack of a single-press trigger that can be directly transmitted through the user, or a single-press trigger through the automatic implement, and an automatic actuation nailing operation mode is generated. Under the demand of the operation mode of the continuous driving nail, whether the operator or the automatic machine only needs to press a single trigger, the nailing piston can be driven to reciprocate in the cylinder, thereby automatically and continuously nailing. Therefore, in the operation mode different from the above-mentioned Restrictive actuation, the operator needs to release the trigger and then press the trigger twice to perform continuous nailing. Therefore, it is possible to save the manual load required for continuously pressing the trigger or the reciprocating control load of the action component of the automatic implement.
進一步的說，在已知的相關技術中，例如美國第7448524號專利揭露利用扳機內部配置一梭動閥，能協同安全滑桿的動作來管制擊釘順序，美國第7931180號專利揭露利用槍體內配置的多個閥元件，能協同安全滑桿及扳機閥的動作來管制擊釘順序，美國第4784302號專利揭露於槍體頭座內設有閥元件來管制高壓空氣的通路流向；美國第5896933號專利甚至於揭露於扳機閥與氣缸之間的槍體內設有多個閥元件來管制高壓空氣連續式驅動(Automatic actuation)的擊釘 順序；但是，這些先前技術所揭露的釘槍，縱使可以執行上述的連續式驅動(Automatic actuation)擊釘操作，但其氣路結構複雜，特別是在執行連續式驅動(Automatic actuation)的快速擊釘的耐久操作下，穩定性欠佳。Further, in the related art, for example, U.S. Patent No. 7,445,524 discloses the use of a shuttle valve to configure a shuttle valve to control the sequence of nails in conjunction with the action of the safety slider. U.S. Patent No. 7,931,180 discloses the use of a gun body. The plurality of valve elements are configured to cooperate with the action of the safety slider and the trigger valve to control the nailing sequence. The US Pat. No. 4,784,302 discloses a valve element in the gun body seat to regulate the passage of high pressure air; US 5896933 The patent even discloses a plurality of valve elements in the gun body between the trigger valve and the cylinder to regulate the high-pressure air automatic actuation of the nail Order; however, the nail gun disclosed in these prior art, even though the above-described automatic actuation nailing operation can be performed, has a complicated gas path structure, particularly in performing a quick actuation of automatic actuation. Under the durable operation of the nail, the stability is not good.
本新型之目的，旨在改善傳統氣動釘槍執行連續式驅動(Automatic actuation)擊釘模式所需的氣路配置過於複雜的問題，以及無法長時間維持穩定及快速擊釘的問題。The purpose of the present invention is to improve the complexity of the gas path configuration required for a conventional pneumatic nail gun to perform an automatic actuation nailing mode, and to maintain stable and fast nailing for a long time.

在圖6a中，揭示切換器4的止擋件41定位於第二位置A2，釋放梭動閥桿32能自由的在第一氣室16a及第二氣室16b之間進行挺位及復位移動，且在主氣室10a內已存在高壓空氣集壓的狀態下，扳機閥2未受按壓前，扳機閥2的閥桿20可以管制主氣室10a的高壓空氣驅動扳機閥2內的一活動閥栓23，使高壓空氣經由第一通道21與第二通道22相連通，進而導引主氣室10a內的高壓空氣至扳機氣路15中；此刻，擊釘活塞13坐落於上移頂點P1而尚未被驅動下 移，復位氣路18經由復位閥孔120連通形成常壓的底層氣缸室12b(通大氣)，使得第一氣室16a形成壓降端，同一狀態下，主氣室10a內的高壓空氣經由挺位氣路17通往第二氣室16b集壓，並且經由高壓空氣通路W通往第三導引孔313，此刻在第二氣室16b集壓的高壓空氣驅動第二端面322，因第一氣室16a內已形成壓降，且可參酌第二端面322的推力面積小於第一端面321的設計要素，使得梭動閥桿32被高壓空氣驅動而由第二氣室16b往第一氣室16a方向挺位移動，令第二管制閥部36關閉第三導引孔313通往第二導引孔312的通路，並令第一管制閥部35開啟第一導引孔311與第二導引孔312相連通，以導引扳機氣路15內的高壓空氣通往頂層氣室14a集壓，藉以驅動主氣閥14緊閉主氣閥口141，避免高壓空氣進入頂層氣缸室12a內，因此可確保擊釘活塞13坐落於上移頂點P1的待擊釘位置。In Fig. 6a, it is disclosed that the stopper 41 of the switch 4 is positioned at the second position A2, and the release shuttle lever 32 can freely perform the positioning and reset movement between the first air chamber 16a and the second air chamber 16b. And the valve stem 20 of the trigger valve 2 can regulate the high pressure air of the main air chamber 10a to drive an activity in the trigger valve 2 before the trigger valve 2 is not pressed in the state where the high pressure air pressure is already present in the main air chamber 10a. The valve plug 23 connects the high-pressure air to the second passage 22 via the first passage 21, thereby guiding the high-pressure air in the main air chamber 10a into the trigger air passage 15; at this moment, the nail-piercing piston 13 is located at the upper apex P1 And have not been driven The reset, reset gas path 18 communicates via the reset valve hole 120 to form a bottom pressure cylinder chamber 12b of normal pressure, so that the first gas chamber 16a forms a pressure drop end.

The first control valve portion 36 closes the passage of the third guide hole 313 to the second guide hole 312, and causes the first control valve portion 35 to open the first guide hole 311 and the second guide. The pilot holes 312 are connected to guide the high pressure air in the trigger air passage 15 to the top air chamber 14a to collect pressure, thereby driving the main air valve 14 to close the main air valve port 141 to prevent high pressure air from entering the top cylinder chamber 12a. It is thus ensured that the nailing piston 13 is seated at the position of the nail to be struck up the apex P1.

Meanwhile, when the nail driving piston 13 is moved down to pass through the reset valve hole 120, the reset valve hole 120 is connected to the top cylinder chamber 12a which continuously collects high-pressure air, and thus, the high pressure of the continuous collecting pressure in the top cylinder chamber 12a is obtained. The air is guided to the first air chamber 16a through the reset valve hole 120 and the reset air passage 18, thereby driving a large thrust area. The first end surface 321 , the high-pressure air thrust force continuously driving the second end surface 322 is smaller than the high-pressure air thrust driving the first end surface 321 , so that the shuttle valve rod 32 is reset from the first air chamber 16 a toward the second air chamber 16 b. .

The road 15 and the top air chamber 14a lead to a pressure relief passage of the outside atmosphere, and at the same time, the shuttle valve rod 32 is reset and moved, and the second control valve portion 36 can be driven to open the third guiding hole 313 and the second guiding hole 312. The passage between them is to guide the high pressure air into the top plenum 14a to collect again.

The passage (which is conventional) causes a pressure drop in the top cylinder chamber 12a. In this state, the nailing piston 13 that has been moved down and completed the nailing can pass the pressurized high pressure air in the return air chamber 10b. The drive is moved up and reset (generally), and when the pinning piston 13 is moved up to the reset valve hole 120 to return to communicate with the bottom cylinder chamber 12b, it can be assembled in the first air chamber 16a at the same time. After the high-pressure air is introduced into the bottom cylinder chamber 12b, and the first air chamber 16a is returned to the pressure drop, the high-pressure air continuously driving the second end surface 322 drives the shuttle valve rod 32 to move again, and returns to the pressing as shown in FIG. 6b. The initial state of the trigger valve.
依此，由於圖6b至圖6e所示動作期間，都沒有釋放扳機閥2的閥桿20，即可返復驅動梭動閥桿32產生往復的挺位及復位移動，據以實現本新型的連續式驅動擊釘操作。相對的，若在圖6e狀態下釋放扳機閥桿20，將回覆如圖6a所示的初始狀態，並且可供再次按壓扳機閥桿20，而重複實施如圖6b至圖6e所示的連續式驅動擊釘操作。Accordingly, since the valve stem 20 of the trigger valve 2 is not released during the operation shown in FIGS. 6b to 6e, the shuttle valve stem 32 can be returned to generate a reciprocating position and a reset movement, thereby realizing the novel Continuous drive nailing operation. In contrast, if the trigger valve stem 20 is released in the state of FIG. 6e, the initial state as shown in FIG. 6a will be replied, and the trigger valve stem 20 can be pressed again, and the continuous mode as shown in FIGS. 6b to 6e is repeatedly performed. Drive the nailing operation.
除此之外，請另合併參閱圖7及圖8，說明本新型還提供一第二種實施例，其與圖1及圖3所示的第一種實 施例的差異在於梭動閥座310與梭動閥桿320之間的閥部及孔位作了變更；進一步的說，其中：In addition, please refer to FIG. 7 and FIG. 8 in combination, and the present invention also provides a second embodiment, which is the first one shown in FIG. 1 and FIG. The difference in the embodiment is that the valve portion and the hole position between the shuttle valve seat 310 and the shuttle valve stem 320 are changed; further, wherein:
梭動閥座310上沒有形成第三導引孔，且梭動閥桿320鄰近第一端面323位置套設至少一個內圍的止氣墊圈39f構成一閥頭325，該閥頭325用以管制第二導引孔312與第一氣室16c的連通時機，以構成所述梭動閥座310上的第二管制閥部360，依此，第二管制閥部360同樣是用於管制槍體1內一高壓空氣氣源通往頂層氣室14a，但第二管制閥部360所管制的高壓空氣氣源是來自於第一氣室16c內。也就是說，當對照於上述圖6b及圖6e狀態下，圖7及圖8中所示的第一氣室16c內同樣是處於壓降狀態，能使梭動閥桿320產生挺位移動。當對照於上述圖6c及圖6d狀態下，圖7及圖8中所示的第一氣室16c內是處於高壓空氣集壓狀態，能使梭動閥桿320產生復位移動。因此，該復位氣路180內的高壓空氣經由第一氣室16c集壓驅動梭動閥桿320產生復位移動時，可經由梭動閥桿320的閥頭325(即第二管制閥部360)開啟第一氣室16c與第二導引孔312相連通，該第二氣室16d內高壓空氣驅動梭動閥桿320挺位移動時，可經由梭動閥桿320的閥頭325(即第二管制閥部360)關閉第一氣室16c與第二導引孔312相連通。The third guide hole is not formed on the shuttle valve seat 310, and the air lock washer 39f of the shuttle valve stem 320 disposed adjacent to the first end surface 323 at least one inner circumference constitutes a valve head 325, and the valve head 325 is used for regulating The second guiding hole 312 is in communication with the first air chamber 16c to constitute the second regulating valve portion 360 on the shuttle valve seat 310. Accordingly, the second regulating valve portion 360 is also used to control the gun body. A high-pressure air source 1 leads to the top chamber 14a, but the high-pressure air source regulated by the second regulating valve portion 360 is from the first chamber 16c. That is, when the first air chamber 16c shown in Figs. 7 and 8 is also in a pressure drop state in comparison with the above-described state of Figs. 6b and 6e, the shuttle valve stem 320 can be moved in the forward position. When the first air chamber 16c shown in Figs. 7 and 8 is in the high pressure air pressure state in comparison with the above-mentioned Figs. 6c and 6d, the shuttle valve stem 320 can be brought into a reset movement. Therefore, when the high-pressure air in the reset air passage 180 is driven to drive the shuttle valve rod 320 via the first air chamber 16c to generate a reset movement, the valve head 325 of the valve stem 320 can be moved (ie, the second control valve portion 360). Opening the first air chamber 16c to communicate with the second guiding hole 312. When the high pressure air in the second air chamber 16d drives the shuttle valve rod 320 to move forward, the valve head 325 of the valve stem 320 can be shuttled (ie, The second regulating valve portion 360) closes the first air chamber 16c and communicates with the second guiding hole 312.
梭動閥座310上的第一管制閥部350，是經由梭動閥桿320上所套設的二個內圍的止氣墊圈39g、39h所框圍形成，其中，止氣墊圈39g能管制第二導引孔312與第一導引孔311的連通時機，因此相同於第一款實施例的第一管制閥部能管制扳機氣路15與頂層氣室14a連通時機的作用，在此不多加贅述。The first regulating valve portion 350 on the shuttle valve seat 310 is formed by enclosing the two inner air retaining washers 39g, 39h that are sleeved on the shuttle valve rod 320, wherein the air lock washer 39g can be controlled The timing of the communication between the second guiding hole 312 and the first guiding hole 311 is the same as that of the first regulating valve portion of the first embodiment, and the timing of the communication between the triggering gas path 15 and the top plenum 14a is controlled. More details.
請專注圖8所示，該梭動閥座310的壁面上還包含形成有一連通於挺位氣路170與第二氣室16d之間的第四導引孔314，該第二端面324係由梭動閥桿320顯露於第二氣 室16d內的兩個環狀梯面324a及324b構成，如此構造上的變更設計，仍能使第二端面324產生與第一款實施例相同的作用。除此之外，有關切換器4的配置方式，均能與上述第一款實施例相同，在此也不多加贅述。Please focus on FIG. 8 , the wall surface of the shuttle valve seat 310 further includes a fourth guiding hole 314 formed between the positional air passage 170 and the second air chamber 16d. The second end surface 324 is formed. Exposed to the second gas by the shuttle valve stem 320 The two annular step faces 324a and 324b in the chamber 16d are constructed in such a way that the second end face 324 can still produce the same effect as the first embodiment. In addition, the configuration of the switch 4 can be the same as that of the first embodiment described above, and will not be further described herein.
本新型透過上述圖7及圖8所示的第二款實施例，將可簡化梭動閥3的配置結構，並且還可將節流閥5直接實施配置於第一氣室16c的端側，進而縮短了復位氣路180的距離，因此與第一款實施例相較，除了兼備第一款實施例所具備的機能與優點之外，第二款實施例相對的還具有簡化結構複雜度及節省加工成本的貢獻。According to the second embodiment shown in FIG. 7 and FIG. 8 above, the arrangement structure of the shuttle valve 3 can be simplified, and the throttle valve 5 can also be directly disposed on the end side of the first air chamber 16c. Further, the distance of the reset gas path 180 is shortened. Therefore, in addition to the functions and advantages of the first embodiment, the second embodiment has a simplified structural complexity as compared with the first embodiment. Save on the cost of processing.
附加說明的是，圖7及圖8所示將節流閥5配置於第一氣室16c的端側，亦可在圖1及圖6a至圖6e所示的第一款實施例中加以體現，而不影響第一款實施例既有的效用。Incidentally, the throttle valve 5 is disposed on the end side of the first air chamber 16c as shown in FIGS. 7 and 8, and may be embodied in the first embodiment shown in FIGS. 1 and 6a to 6e. Without affecting the usefulness of the first embodiment.
